$19.95 for a three pack at costco. machined aluminum body. 200 lumens. Brighter than most car headlights. About 5" long. Runs on three triple A's. I live on a 12 acre farm that is mostly field. These things give you a weird "power trip" feeling due to the incredible brightness. With a single light I can see anything anywhere on my property easily. And the thing can be used as a weapon as well. And did I mention $19 for a threepack.
